This listing is for a brand new thermostat for a Johnson or Evinrude outboard.  It also replaces thermostats for several Mercury/Mariner and Force motors, and we have separate listings for those.  Sierra packages this thermostat with both Mercury and OMC applications on it, and we may have either one at any given time.  If you receive a thermostat with Mercury applications listed on it, don't be concerned.  As long as the part # is 18-3553, it is the correct part for your OMC motor listed below.
It replaces OMC #434841, 378065, 393659, 508626, 5005440.
Temperature rating is 143 degrees.
This thermostat fits the following engines:
